what to expect

Completing the entire 2,190 miles of the Appalachian Trail (A.T.) in one trip is a mammoth undertaking. Each year, thousands of hikers attempt a thru-hike; only about one in four makes it all the way.

  • A typical thru-hiker takes 5 to 7 months to hike the entire A.T.
  • After deciding when and where to begin and then registering your thru-hike, you will need to plan your resupply points and know the camping regulations along the A.T.
  • Learn the camping regulations along the A.T. and the ATC's expectations for hikers who want to be officially recognized as a 2,000-miler.
  • In addition to these logistics, physical and mental preparations become important factors in a successful thru-hike. Learn more about all these subjects below.

where to start

North Bound Hike Compass Icon


Starting in Georgia has long been the most popular place to start a thru-hike. But "popular" has led to "crowded" between March 1 and April 15. During this time, the southern end of the A.T. becomes a continuous stream of hikers during the day, with dozens of hikers clustered around campsites at night. The "nobo" hiker typically encounters wintry conditions in March and parts of April and hot, humid conditions in summer. Katahdin provides a dramatic finale; hikers should plan to arrive before October 15.



Flip Flop

Increasingly, hikers are choosing to start somewhere in the middle of the Trail.  Generally, these itineraries offer a gradual progression from easier to more difficult terrain and more frequent resupplies. You can also avoid crowded conditions on the Trail and sold-out services in trailside villages. A mid-Trail start also enables you to follow more favorable weather conditions and at the same time help conserve the Trail.

Starting a thru-hike in Maine is by far the most challenging way to tackle the Trail. Katahdin, the Trail's northern terminus, is regarded as the most difficult mountain on the entire A.T. The route through Maine involves extensive climbing and scrambling over steep, rocky, root-covered and muddy terrain. A heavy pack is required due to the distance between resupply points. It’s best undertaken only by experienced and fit hikers.

Maps and Guides


Thru-hiking guide and planners, official A.T. hiking maps, and lots of cool A.T.-themed items  are available from the Ultimate Appalachian Trail Store.

voluntary thru-hiker registration

The voluntary thru-hiker registration is a tool that helps prospective thru-hikers share their start dates with other thru-hikers and plan their itinerary in order to avoid the social and ecological impacts of overcrowding.

Thru-Hiking Camping


Whether you're pitching a tent in a designated campsite or you're dispersed camping, minimize your impacts and know the camping regulations on the A.T.


Thru-Hiking Shelter


There are more than 250 backcountry shelters located along the Trail for backpackers on a first-served basis. Not only are they the best places to stay dry, but they reduce hikers’ impact on the Trail environment.

Permits & Regulations

No fees or paid permits are required to access the A.T. for simply walking, but some New England campsites impose fees, and you must obtain permits for backcountry camping in two national parks on the A.T.


Report an incident

While the Appalachian Trail is a relatively safe place to visit, that does not mean that there are not potential dangers while you are hiking or camping. If you see something, say something — this will help us keep the A.T. as safe as possible for our visitors.


Physical Preparation Keith Fosket

Physical Preparation

A thru-hike is a great adventure, and anyone who can walk and has the time and desire can do it. But thru-hiking is a demanding endeavor and requires rigorous physical preparation.



Mental Attitude

While physical fitness will certainly give you an edge and make your first weeks on the Trail easier, in the long run, mental attitude is more important.

Workshops & Advice

2,000-milers who are willing to share their experiences and advice, as well as conduct workshops about thru-hiking, can offer valuable opportunities to learn about long distance hiking and help you avoid common mistakes.




The most predictable mistake thru-hikers make when they start is carrying too much stuff. Put as much effort into determining what you don't need as what you do.



Food & Resupply

There's no need to carry more than 3 to 6 days of food on most parts of the A.T. Thru-hikers have techniques for resupplying in towns along the way.

report a hike

Section hikers and thru-hikers who complete the entire A.T. can report their journeys to us by filling out the 2,000-miler application. Those who submit their applications will be added to our roster of 2,000-milers and will receive a certificate of recognition, an A.T. patch, and an accompanying 2,000-miler “rocker” patch. Each year the names of those who have reported hike completions in the previous 12 months are published in the Spring issue of A.T. Journeys magazine. Our comprehensive online 2,000-miler listing is updated periodically.
